To apply the negative of an image to be printed to a printing form (1, 1701), the receptors or cells (7, 1704) of the printing form are first made to have the maximum size required for transfer of the necessary quantity of ink to a substrate (12) and the cells are then, selectively, filled with a flowable, solidifiable substance (9, 1704a), in accordance with the printed image. The quantity of substance (9) introduced into gravure cells (7) can be inversely proportional to the quantity of ink to be transferred to the substrate (12) and injected, for example by a spray of ink jet device similar to an ink jet printer, into the cells under control of a control unit (M), the melted substance solidifying upon contact with the gravure form (1). In a screen printing from, the substance can fill the interstices of the screen, forming the cells (1704). After printing, the form which, if a gravure form, preferably is a seamless ceramic cylinder, can be re-programmed by re-use by cleaning the form to be free from ink, then melting-out the solidified prior substance, assisted for example by wiping, suction, compressed air or hot air blowing or blotting, and then re-imaging the printing form in accordance with new image information by introducing molten, then solidifying substance into the cells in accordance with the new image information.
